Publication number: 20160264440Abstract: A bioreactor has a biofilm supporting bed with at least two types of media. An upper media is relatively porous, preferably porous enough to admit particles of a lower media. In use, wastewater flows downwards through the bed. Soluble nitrogen is reduced in the upper media and converted into nitrogen gas. Nitrogen gas bubbles rise through the upper media and escape from the bed. Selenium is reduced in the lower media and converted into elemental selenium. The elemental selenium is released periodically by backwashing the bed, which may cause fluidization or other expansion of the lower media into the upper media.Type: ApplicationFiled: December 15, 2015Publication date: September 15, 2016Inventors: Nelson FONSECA, Jeffrey Ronald CUMIN, Joel Alexander CITULSKI

Publication number: 20160264441Abstract: A method for biologically treating effluent involves pouring the effluent into a basin in which mobile supports are submerged for developing a biofilm and for carrying out a treatment by fixed fluidized bed, aerating the effluent in the basin with a distribution of air flow, from the bottom of the basin, according to a floor configuration, the aeration supplying air for treating the nutrients, and keeping the supports moving, regulating the aeration to modulate the air flow depending on at least one parameter taken from the following parameters: the residual oxygen concentration, and/or the concentration of oxygen and the concentration of N—NH4, and/or the permitted load; modifying the distribution of the air supply from the floor configuration to a spiral flow configuration when the operating conditions result in an air flow lower than a minimum air flow required to keep the mobile supports moving in the floor configuration.Type: ApplicationFiled: October 30, 2014Publication date: September 15, 2016Inventors: Laure GRAVELEAU, Troy HOLST

Publication number: 20160264443Abstract: Wastewater such as water discharged by the human body and domestic wastewater which is produced in a confined space, can be treated and recovered with efficiency by using a simple apparatus. Specifically, hardness components of water-to-be-treated are removed with a softening apparatus. Subsequently, electrolysis is performed with a high-temperature high-pressure electrolysis apparatus in order to decompose and remove organic substances, urea, ammonia, and the like. The electrolyzed water is desalinated with a desalination electrodialysis apparatus in order to produce product water and a salt-concentrated liquid. The salt-concentrated liquid is further treated with an acid-alkali production electrodialysis apparatus in order to produce desalinated water, an acid solution, and an alkali solution. The acid solution is used as an agent for regenerating the softening apparatus. The alkali solution is used as an agent for converting the softening apparatus into Na-type.Type: ApplicationFiled: November 22, 2013Publication date: September 15, 2016Inventors: Yukitaka MATSUMOTO, Hideki KOBAYASHI, Nobuhiro ORITA

Publication number: 20160264446Abstract: Disclosed herein is a process for producing foam glassy materials. The process includes providing a precursor foam glassy formulation, the precursor foam glassy formulation comprising a micronized glassy material, in which the micronized glassy material being any one or any combination of ceramic opaque frits, transparent frits, flux frit, glazes, waste from kaolin processing, porcelain waste products, slag, cement, concrete, waste tile products and a foaming agent. The precursor foam glassy formulation is then processed to form a foam glassy product by firing the precursor foam glassy formulation to a temperature in a range from about 800° C. to about 900° C., followed by a step of annealing, followed by a step of cooling to produce a foam glassy product. The chemical, mechanical, physical properties of the final foam glassy material may be adjusted or tuned by adjusting the amounts of the various constituents making up the precursor foam glassy material.Type: ApplicationFiled: March 13, 2015Publication date: September 15, 2016Inventors: Abbas YOUSSEFI, Amir Hossein YOUSSEFI

Publication number: 20160264447Abstract: A method for producing a blank from titanium-doped, highly silicic-acidic glass having a specified fluorine content for use in EUV lithography is described, in which the thermal expansion coefficient over the operating temperature remains at zero as stably as possible. The course of the thermal expansion coefficient of Ti-doped silica glass depends on a plurality of influencing factors. In addition to the absolute titanium content, the distribution of the titanium is of significant importance, as is the ratio and distribution of additional doping elements, such as fluorine. In the method, fluorine-doped TiO2—SiO2 soot particles are generated and processed further via consolidation and vitrifying into the blank, and, by flame hydrolysis of input substances containing silicon and titanium, TiO2—SiO2-soot particles are formed, exposed to a reagent containing fluorine in a moving powder bed, and converted to the fluorine-doped TiO2—SiO2-soot particles.Type: ApplicationFiled: November 6, 2014Publication date: September 15, 2016Inventors: Stefan OCHS, Klaus BECKER
